About five kilometers from De Groene Hartelijkheid lies the picturesque town of Oudewater. The historical facades along the canals in the town centre are well worth a visit. The world-famous Heksenwaag explains the history of the witch prosecution in Europe. Touwmuseum De Baanschuur gives an insight in the rope industry, to which Oudewater owed her prosperity in the old days. Every Wednesday from 11am thru 4pm there is a market.
De Groene Hartelijkheid is the ideal starting point for hikes, bike and canoeing trips in the vast polder landscape of the Groene Hart. There are various hiking trails in the area, such as the Pelgrimspad. The Gouden Eeuw Driehoek is a bike trip linking the three historical towns of Gouda, Schoonhoven and Oudewater. The river Vlist, which is close-by, is suitable for canoe trips. Bikes and canoes are for hire at the kanocentrum in Haastrecht.
